摘　　要：为了提升乘客出行体验,实现运力与运输需求的匹配,同时降低城轨站台拥挤度,文章基于历史客流需求对轨道交通多交路列车开行方案的优化和多交路运行计划自动编制方法进行了研究,提出了一种基于站台拥挤度的城市轨道交通开行方案优化方法。首先,基于历史断面客流和OD(起止点)客流,重点对站台拥挤度进行建模分析,以站台最大拥挤度最小和列车运能运量最佳匹配为目标,构建了多交路列车开行方案的多目标整数规划模型;然后,利用遗传算法求解得到最优开行方案,并将最优开行方案落实到运行计划上,实现了多交路运行计划的自动编制。文章结合某轨道交通线路客流数据,通过仿真验证了方法的有效性。仿真结果表明,基于该方法自动编制的多交路运行计划的站台最大拥挤度比人工编制的运行计划的低了约20.6%,因此算法具有更好的实用价值。In order to enhance passenger travel experience,align transportation capacities with demands,and alleviate platform overcrowding at metro stations,this paper proposes a methodology for optimizing train operation plans based on platform crowding degree in rail transit systems,as a result of studies focusing on optimizing multi-route train operation plans based on historical passenger flow demands and automatically scheduling multi-route train operation for these systems.First,a modeling analysis was performed using historical sectional passenger flow and origin-destination(OD)passenger flow data,prioritizing platform overcrowding degree.A multi-objective integer planning model was constructed for the multiple-route operation of trains,aiming to minimize the maximum platform crowding degree and achieve the optimal match between train capacities and transportation volumes.Next,a genetic algorithm was utilized to derive the optimal operation plan through a solving process,and this optimal plan was integrated into subsequent operation scheduling,facilitating the automatic compilation of multi-route operation schedules.Finally,the effectiveness of the proposed approach was validated through simulations based on historical passenger flow data from a rail transit line.The simulation results indicated that the automatically-compiled multiple-route operation schedules based on this method lowered the maximum platform crowding degree by 20.6%,compared to manually-compiled ones,highlighting the algorithm's value in practical applications.
